If you haven’t tried out any of the Google Apps Scripts already created for your convenience, I challenge you to find one to try over your winter break. And, even if you are a veteran, try a new one.
My current favorites are Choice Eliminator and Awesome Tables for Google Sites. They have made my productivity increase.
A recent find was Alice Keeler’s Group Maker. It automatically creates groups from a spreadsheet. And, what’s even better is that you can use it with Google Classroom to make small groups in Classroom – my most wished-for feature!
